Marek Gryta received his Diploma in Chemical Engineering in 1988 from the Technical University of Szczecin, Poland, and his Ph.D. in 1995 from the same institution. Currently, he is a Full Professor of chemical technology at the West Pomeranian University of Technology in Szczecin, Poland. His main research interests focus on the study of membrane processes applied to water desalination and wastewater treatment. He published a number of scientific articles (over 300) and about 50 patents in this research area, with the majority of these being associated with the membrane distillation process. His teaching duties include lectures concerning inorganic chemistry, chemical and environmental analyses, separation processes, and technical drawing. He realized several research projects focusing on the application of membrane processes for water treatment in power plants and industry. His most recent research project involves the use of membrane distillation for the separation of brines contaminated by oil and surfactants. This major problem comprises the durability of hydrophobic membranes (fouling/scaling and wettability), particularly during the treatment of brines containing various surface-active contaminants. In this project, the polypropylene membranes were applied, and their performances will be confirmed by long-term MD studies (over several months).
